- Marcus Livius Drusus,the name of two Republican politicians:
- Marcus Livius Drusus (consul) (died 108 BC), father
- Marcus Livius Drusus (tribune) (died 91 BC), son
- Marcus Livius Drusus Claudianus (died 42 BC), adopted from the Claudii (hence Claudianus) by the tribune and the father of Livia Drusilla, Augustus' third wife
- Marcus Livius Drusus Libo (born 1st-century BC), adopted by Claudianus from the Scribonii Libones (hence Libo), consul in 15 BC
Male members of other clans whose mother belonged to the Livii Drusi and had given her son the agnomen Drusus in commemoration of that fact, even though he was not by law of the Livii Drusi. The most noted example is perhaps the Claudii Drusi, who were given the name Drusi by their mother Livia Drusilla. They were not Livii Drusi, but a new branch of the Claudii.
